MFC r300222: Fix delaying requests to unknown virtual ports 2s after init.
This code was originally implemented 7 years ago, but never really worked
due to trivial error. I think this functionality may be not required.
Initiators supporting optional periodic command status checks detected
those terminated commands and retried them 3 seconds later. But thinking
about less featured initiators and the fact that it is our race makes
virtual ports "unknown" it may be good to have this feature.
